Saturação de creatina em indivíduos fisicamente ativos: técnica eficaz ou desnecessária?
Revista Brasileira de Nutrição Esportiva, 2016 A creatina é um nutriente natural, de procedência animal encontrada em carnes vermelhas e peixes. É um suplemento que vem sendo estudado desde a década de 90, onde foi notado seu uso frequente por atletas de elite nas olimpíadas de Barcelona em 1992.

The Essence of ATP Coupling [PDF]
ISRN Biochemistry, 2012 The traditional explanation of ATP coupling is based on the raising of the equilibrium constants of the biochemical reactions. But in the frames of the detailed balance, no coupling occurs under thermodynamic equilibrium. The role of ATP in coupling is not that it provides an increase in the equilibrium constants of thermodynamically unfavorable ...

Method of detecting and counting bacteria in body fluids [PDF]
, 1973 A novel method is reported for determining bacterial levels in urine samples, which method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of non-bacterial ATP.

Nucleotide-, chemotactic peptide- and phorbol ester-induced exocytosis in HL-60 leukemic cells [PDF]
, 1990 Undifferentiated and differentiated HL-60 leukemic cells possess nucleotide receptors which functionally couple to phospholipase C via pertussis toxin-sensitive guanine nucleotide-binding proteins (G-proteins).

A new type of Na+-driven ATP synthase membrane rotor with a two-carboxylate ion-coupling motif [PDF]
, 2013 : The anaerobic bacterium Fusobacterium nucleatum uses glutamate decarboxylation to generate a transmembrane gradient of Na+. Here, we demonstrate that this ion-motive force is directly coupled to ATP synthesis, via an F1Fo-ATP synthase with a novel Na ...

Regulation of metabolic pathways PVY-RNA biosynthesis in tobacco: glycolytic pathway
Plant Protection Science, 2004 Tobacco plants infected with potato virus Y were studied at the stage of acute infection. Key enzymes of the glycolytic pathway, their regulation and the content of involved intermediates were monitored.

Requirement of a Membrane Potential for the Posttranslational Transfer of Proteins into Mitochondsria [PDF]
, 1982 Posttranslational transfer of most precursor proteins into mitochondria is dependent on energization of the mitochondria. Experiments were carried out to determine whether the membrane potential or the intramitochondrial ATP is the immediate energy ...

Structure of a bacterial ATP synthase
bioRxiv, 2018 ATP synthases produce ATP from ADP and inorganic phosphate with energy from a transmembrane proton motive force. Bacterial ATP synthases have been studied extensively because they are the simplest form of the enzyme and because of the relative ease of ...

Sac1p mediates the adenosine triphosphate transport into yeast endoplasmic reticulum that is required for protein translocation. [PDF]
, 1995 Protein translocation into the yeast endoplasmic reticulum requires the transport of ATP into the lumen of this organelle. Microsomal ATP transport activity was reconstituted into proteoliposomes to characterize and identify the transporter protein.
